Jupiter's interior is
a sea of liquid and metallic hydrogen
What are the gas Giant atmospheres made of
hydrogen and helium gases
Great Red Spot on Jupiter
on-going massive hurricane-like storm that is two-times the size of Earth; wind speeds up to 540 km/hr
All four gas giants have
rings
What are the gas Giant cores made of
rocks and metals
What is the core of Jupiter made up of
solid, rocky iron core
Characteristics of a Gas Giant
More massive than terrestrial; less dense than a terrestrial too.
what do the orange, gray, blue and white bands on Jupiter suggest

Outer Planets
five planets farthest from sun: Jupiter, Saturn, Uranus, Neptune and Pluto
why did Jupiter not become a star
it did not have enough mass to allow nuclear fusion to begin
Why did Jupiter keep its atmosphere
Gravity was greater, did not allow gases to escape into Universe; distance from sun kept it from boiling off
four major moons of Jupiter
Io (volcanically active), Europa (ice), Ganymede (largest), Callisto (cratered)
